Chrysanthemum plant named ‘Amadora Red’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Amadora Red’, characterized by its compact, upright, outwardly spreading and rounded plant habit; freely branching habit; dense and full plant habit; uniform, freely and early flowering habit; and large decorative-type inflorescences with dark red-colored ray florets.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘AMADORA RED’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the name ‘Amadora Red’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in October, 2004 of a proprietary selection of Chrysanthemum×morifolium identified as code number GE 96 4211CARE, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number JU 00 2670GROR, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in August, 2005.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2006. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Amadora Red’. These characteristics in combination distinguish ‘Amadora Red’ as a new and distinct Chrysanthemum cultivar:

-   -   1. Compact, upright, outwardly spreading and rounded plant         habit.     -   2. Freely branching habit; dense and full' plant habit.     -   3. Uniform, freely and early flowering habit.     -   4. Large decorative-type inflorescences with dark red-colored         ray florets.

Plants of the new Chrysanthemum differ from the female parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum have lighter green-colored         leaves than plants of the female parent selection.     -   2. Plants of the new Chrysanthemum flower earlier than plants of         the female parent selection.     -   3. Plants of the new Chrysanthemum and the female parent         selection differ in ray floret color as plants of the female         parent selection have darker red-colored ray florets.

Plants of the new Chrysanthemum differ from the male parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flower earlier than plants of         the male parent selection.     -   2. Plants of the new Chrysanthemum and the male parent selection         differ in ray floret color as plants of the male parent         selection have orange-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Helen’, disclosed in U.S. Plant Pat. No. 9,793. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Helen’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were more rounded than plants         of ‘Helen’.     -   2. Stems of plants of the new Chrysanthemum were more flexible         than and not as brittle as stems of plants of ‘Helen’.     -   3. With development, ray floret color of plants of the new         Chrysanthemum was lighter in color than ray floret color of         plants of ‘Helen’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Amadora Red’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the summer and autumn under conditions and practices which approximate those generally used in commercial production. During the production of the plants, day temperatures ranged from 25° C. to 30° C. and night temperatures ranged from 15° C. to 20° C. Plants were 15 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
